6 The UCPD is configured by software as either a Downstream Facing Port (DFP) or an Upstream Facing Port (UFP). In DFP mode, assuming no cable flip, CC1 is connected to Rp. The value of Rp indicates the value of the default power that the DFP can source on Vbus. In DFP mode, ...
This is the common case for most upstream facing ports, like those found in PCI Express endpoints. The figure shows an example 4-lane implementation of a multilane PIPE solution. The signals that can be shared are explicitly shown in the figure while signals that replicated for each lane are...
The ChargerLAB / Power-Z KM003C is an inline device placed between the downstream facing port (DFP) of a host and the upstream facing port (UFP) of a device. Either component can act as the source and sink in terms of power delivery. It is used for voltage and current detection...
7, 02/2019 36 NXP Semiconductors ERR003733 ERR003733 ARM: 751480—Conditional failed LDREXcc can set the exclusive monitor Description: A conditional LDREX might set the internal exclusive monitor of the Cortex-A9 even when its condition fails. So, any subsequent STREX that depends on this LDREX...
Projected Impact: The count of events 0x0C and 0x0D are not 100% precise when using the Performance Monitor counters, due to the ISB being counted in addition to the real software changes to PC (for 0x0C) and immediate branches (0x0D). The erratum also causes the corresponding PMU...
